STEAM-TRAP.

SPECIFICATION forming part of Letters Patent No. 619,207, dated February '7, 1899.

Application filed August 2, 1898. Serial No- 687,477. (No model.)

To (LZZ whmn it may concern.-

Be it known that I, ANTOINE MUSNICKI, engineer, a citizen of Russia, residing at 25 Rue Dossin, Liege, in the Kingdom of Belgium, have invented certain new and useful .Improvements in Steam-Traps, of which the following is a clear description.

The improved steam-trap which forms the subject of this invention consists, essentially, of two pipes, one of which is arranged in the interior of the other and acts as the steamconduit, or of one pipe divided into two compartments.

The invention is illustrated in the accompanying drawings, wherein Figures 1 and 2 are respectively longitudinal transverse sections of one form of the invention, and Figs. 3 and 4 are similar views of a modification thereof. Figs. 5 to 9 are views illustrative of the mode of action and arrangement of the improved steam-trap.

In the form illustrated in Figs. 1 and 2, B is the outer pipe, and C the inner pipe, forming the steam-conduit. This steam-conduit is provided with outlets F F F, &c., in the form of traps, provided with deflectors E E E Fig. 1,'which direct the water from the steam-conduit J through said falls or traps into the water-chamber J. These falls and their deflectors are constructed in that form of the invention shown in Figs. 1 and 2 as follows: Convexities and incisions are made alternately low down, as at E, on the right side, as at E or on the left, as at E', Fig. 2, in the sides of the pipe 0, so that traps E E E, &c., Fig. 1, open into the interior of the pipe 0, thereby forming passages for the water condensed from the steam. The two pipes 13 and 0, arranged in the manner hereinbefore described, are held firmly at both ends by means of the flanged pipes A and bolts and nuts D and made steam-tight both inside and outside.

In Figs. 3 and 4 a modification is illustrated in which instead of an inner pipe 0 the pipe 13' is divided into two compartments by means of a fiat partition-wall C, so arranged that a separation of the steam-chamber J from the water-chamber J is likewise obtained, as in Figs. 1 and 2. In this case the deflectors are indicated by the letter G and the outlets by the letter H. In order that under this arrangement the partition-wall O of the chambers J and J may be fortified against the steam pressing on the deflectors G, internallyscrew-threaded pipes L, into which bolts M and N are screwed, are provided at suitable places between the flaps G. The partitionwall 0 is, moreover, fastened to the sides of the pipe B by means of rails or angle-irons K, as preferred.

The essential feature of each form of the invention is that no kind of obstacle is arranged in the steam-conduit itself, but only on the partition-surface of the two chambers that is to say, on the bottom of the steamchamber J so that the passage of the steam is to a certain degree unobstructed. The water carried into the steam-conduit J falls naturally into the lower collecting-chamber J and is there no longer afiected by the velocity of the steam. It flows, therefore, quietly away through the collecting-pipes J.

In order that the rational arrangement of the separation of the condensed water may be clear, I have introduced a regulating apparatus. (Shown in Fig. 5.) This consists of a pipe S, externally screw threaded throughout its length and which by means of the nut U can be screwed from end to end into a steam-conduit pipe T. It, now, steam be allowed to enter the pipe T, it will be observed that the pipe receives steam which at first is quite moist and toward the middle or center becomes dry. (See the arrows in Fig. 6.) Again, proceeding from the center to the side of the pipe S the steam will again be more moist. In Fig. 7 I have illustrated this by means of circles, the lighter lines indicating dry steam and the heavier lines moist steam, the heavier the line the more moist the steam. In reality under the horizontal arrangement the separation of the water only occurs (shown in Figs. 1 to 4) by reason of the different velocities of the water and steam and the weight of the water and is consequent upon the fact that the distribution of the condensed water extends over a surface of a crescent shape, as shown in Fig. 8that is to say, over a zone which becomes denser at the lower part of the side of the pipe.

From the foregoing description it will be clearly seen that the arrangement of the outlets F F F or H H. H and of the deflectors E E E or G G G corresponds exactly with the requirements of a rational separation of the condensed water.

It should be further mentioned that in a pipe-conduit, such as O P Q R, as shown in side elevation in Fig. 9 and in WhlCh'thG passage of the steam is in the direction of the arrows, the insertion of the separator can only be made in the section P, not, as indicated by dots, in the section B and especially not in the section Q.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. A steam-separator consisting of a pipe or other similar structure having a series of orifices in its wall and deflectors projecting inwardly from said wall and each extending over an orifice, said orifices and their deflectors being situated relatively remote from the path of maximum steam-flow and another pipe provided with suitable discharge-openings and having communication with said first-named pipe through said orifices, substantially as described.

2. A steam-separator consisting of a pipe or other similar structure having a series of orifices in its wall and deflectors projecting inwardly from said wall and'each extending.

tors being situated relatively remote from the path of maximum steam-flow and another pipe provided with suitable discharge-openings surrounding said first-named pipe, and having communication therewith through said orifices, substantially as described.

3. The combination, with a substantially horizontal steam-pipe or other similar conductor, of a steam-separator situated therein and consisting of two pipes the one inclosed by the other and proximating each other at their respective uppermost portions, and bracing means between the lowermost portions of said pipes, the inclosed pipe being provided with a series of orifices in the lowermost portion of its wall and deflectors projecting inwardly from said Wall and each extending over an orifice and the other or inclosing pipe having'a suitable discharge opening or openings, substantially as described.

In testimony that I claim the foregoing I have hereto set my hand this 18th day of July, 1898.

ANTOINE MUSNICKI.
